Band-stop with defined notch depth
Table 7- 4 Example of band-stop with defined notch depth
STARTER filter parameters
Blocking frequency f = 500 Hz
Sp
Bandwidth f = 500 Hz
BB
Notch depth K = -20 dB
Reduction Abs = 0 dB
Simplified conversion to parameters for general order filters:
● No reduction or increase after the blocking frequency
● Defined notch at the blocking frequency K[dB] (e.g. -20 dB)
● Numerator natural frequency f
● Numerator damping:
● Denominator natural frequency f
● Denominator damping:
